You need to find the total surface area which is 21249.73271
Then times each option (a,b,c,d) by pi to see if you get 21249.7321
6.4 pints a minuet. this is the answer because 8 gallons is 64 pints, there are 60 minuets in an hour so 64/60 is 6.4 pints.
If you know the total length, and the length of one part, and you're trying to find the other part, just subtract.
81-53=28
bc=28
So each time, 24/12 or $2 was deducted per trip
he has 30-24=$6 left
$6/$2=3, he has 3 trips left
I wonder what your question is
Hope this helps!
1. 6
2. 64
